Giganotosaurus
          
        
        
          means “giant southern
        
        
          reptile”, and this dinosaur was big;
        
        
          in fact it may have been larger than
        
        
          
            T. rex
          
        
        
          . However, the two never met
        
        
          as
        
        
          
            Giganotosaurus
          
        
        
          was roaming some
        
        
          10 million years before
        
        
          
            T. rex!
          
        
        
          Big and bold
        
        
          
            Age of the dinosaurs
          
        
        
          
            It’s a new find!
          
        
        
          
            Giganotosaurus
          
        
        
          bones were first
        
        
          unearthed in Argentina in the
        
        
          early 1990s, but no complete
        
        
          skeleton has ever been found.
        
        
          Where did
        
        
          
            Giganotosaurus
          
        
        
          live?
        
        
          It’s difficult to imagine just
        
        
          how big and heavy a fully
        
        
          grown
        
        
          Giganotosaurus
        
        
          really
        
        
          was. It’s thought to have been
        
        
          as heavy as about 125 adult
        
        
          humans. That’s a lot
        
        
          of people!

          Giganotosaurus
        
        
          would have
        
        
          had a keen
        
        
          sense of smell
        
        
          and excellent
        
        
          eyesight.
